I actually really like it. It's way more interesting that I thought it would be.
A guy (Jun) works as a partimer at a bar. This bar has some special days with shows. Jun is actually a sadist for a show on Sundays (but he's not an active sadist in his personal life - until he meets the COO). One customer (Fumitaka) who happens to be a COO in a big company is a masochist and falls for him. Fumitaka helps Jun to overcome his issues and traumas from the past (caused by his step brother) and they end up together (+ Fumitaka proposed to Jun in the end.)
BTW Fumitaka is masochistic seme and Jun is sadistic uke. It's seriously interesting.
